This example demonstrates a scatter plot of flower measurements, encoding bloom length and stem length along the axes while using distinct symbols to represent different flower species. It shows how D3 v7’s `scaleOrdinal`, `symbolsFill`, and `symbol` APIs can map categorical data to visual shapes, accompanied by a custom legend built with reusable ES6 modules. The visualization loads CSV data from a GitHub repository, parses it with `csvParse`, and renders the plot across the full browser window using modular functions for axes and the legend.
